A 9.72-kg ball swings rapidly in a complete vertical circle of radius 3.88 m by a light string that is fixed at one end. The ball moves so fast that the string is always taut and perpendicular to the velocity of the ball. As the ball swings from its lowest point to its highest point, how much work is done by gravity? Give your answer in Joules to three significant figures.
The tension in each rope of a swing at the lowest point is 412 N when a 36.0-kg girl is swinging. The two ropes are each 3.06 m long. What is the girl's speed at the lowest point?
A Ferris wheel is a vertical, circular amusement ride with radius, R = 5 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates so that riders move at a constant speed, v = 5 m/s. Consider a rider whose mass, m = 70 kg. Assume that the acceleration due to gravity, g = 10 m/s₂. H B * L. How much work does the force exerted by the seat do on the rider as they move from point E to point ? O None of these, because the rider's speed does not change O 3500) O-3501 O-3500
A physics student ties a ball with a mass 0.30kg to a string which can exert a maximum force of 41 N without breaking. The student swings the ball in a circle with a radius of 0.91 m, slowly increasing the speed until the string breaks. The circle is oriented vertically so that the ball moves up and down while traveling in a circle. What is the speed of the ball as the string breaks?

9. A student is skateboarding down a ramp that is 6.0 m long and inclined at 18° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 2.6 m/s. Neglect friction and find the speed at the bottom of the ramp.
A light, rigid rod is 77.0 cm long. Its top end is pivoted on a frictionless, horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speedat the bottom is required to make the ball go over the top of the circle? Answer : 5.49 m/s
A knight has an idea to break into a fortress by knocking a wall down with a rolling boulder. The plan is to roll the boulder from the top of a hill to hit the wall at the bottom of the hill. The boulder will need to have a speed of 20.0 m/s to break the wall. What is the minimum height the hill can have for the knight’s plan to succeed? (Assume the hill is frictionless and that the numerical answer you give is in meters)
